Abstract

A composition comprising an ethylene-based polymer, wherein the ethylene-based polymer comprises the following properties: a) an Mw(abs) from 130,000 to 162,000 g/mol; b) a melt index (I2) from 1.5 to 3.0 g/10 min; c) an ADF LS from 0.350 to 0.450 for molecular weight ≥500,000 g/mol.

Claims (13)

1. A composition comprising an ethylene-based polymer, wherein the ethylene-based polymer comprises the following properties:

a) an Mw(abs) from 130,000 to 162,000 g/mol;

b) a melt index (I2) from 1.5 to 3.0 g/10 min; and

c) an ADF LS from 0.350 to 0.450 for molecular weight ≥500,000 g/mol.

2. The composition of claim 1 , wherein the ethylene-based polymer further comprises an ADF IR from 0.200 to 0.250 for molecular weight ≤15,000 g/mol.

3. The composition of claim 1 , wherein the ethylene-based polymer further comprises an ADF DV from 0.180 to 0.240 for molecular weight ≥200,000 g/mol.

4. The composition of claim 1 , wherein the ethylene-based polymer further comprises an ADF DV ≤0.210 for molecular weight ≥200,000 g/mol.

5. The composition of claim 1 , wherein the ethylene-based polymer has a density is from 0.923 to 0.927 g/cc (1 cc=1 cm 3 ).

6. The composition of claim 1 , wherein the ethylene-based polymer is an LDPE.

7. The composition of claim 1 , wherein the composition comprises a second ethylene-based polymer.

8. An article comprising at least one component formed from the composition of claim 1 .

9. A film comprising the composition of claim 1 , wherein the film has a 45° gloss >72% and a 2% MD secant modulus >30,000 psi for a 2.0±0.3 mil film thickness.

10. A film comprising the composition of claim 1 , wherein the film has a ratio of MD shrink tension to CD shrink tension of less than 7.0 and a CD shrink tension greater than 0.9, each for a 2.0±0.3 mil film thickness.
